To make a frequency table, you will need to find the lowest and highest average number of movies.
Numbers go from 0.5 to 4.5.
And example of frequencies you could use are:
0-0.9 (1)
1-1.9(5)
2-2.9(5)
3-3.9(2)
4-4.9(1)
The frequencies are in parentheses beside the intervals.
I do not know because i’m not good at math
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
(-1,1)(1,4)
slope = (4 - 1) / (1 - (-1) = 3/(1 + 1) = 3/2
y = mx + b
slope(m) = 3/2
use either of ur points....(1,4)...x = 1 and y = 4
now sub and find b, the y int
4 = 3/2(1) + b
4 = 3/2 + b
4 - 3/2 = b
8/2 - 3/2 = b
5/2 = b
equation is y = 3/2x + 5/2...but we need it in standard form
y = 3/2x + 5/2
-3/2x + y = 5/2.....multiply both sides by -2
3x - 2y = -5 <==== ur standard form equation
Required algebraic expression is 8/(x - m)
